Application filed .Tune 2, 1913. Serial No. 771,162.

To all wit-0m t may concern Be it known that we, Hanni A. Torrita, d r.,PETER S'rovnn, J r., and Winnniiir MUNZ, citizens of the United States,and residents of the city of Philadelphia, county of Philadelphia, andState of Pennsylvania, have invented a Machine for Making TessollatedLinoleum, of which the following is a specii'ication.

Our invention relates to the manufacture of tessellated linoleum fromgranulated composition and its leading object is to produce fabricsembodying the complete design by a comparatively simple machine havingthe parts for performing the several functions connected so as to act insynchronous rela tion.

ln the accompanying drawings, Figure 1 is a part sectional pla-n view ofa machine embodying our improvements; Fig. 2 is a side elevation of thesame; Fig. 3 1s a side elevation of a section of the machine showw ingdetails of the construction for reciproeating the tr ys; Fig. 4 is asectional view taken on the line 4-4 of Figs. 2 and 3; Fig. 5 is a sideelevation of mechanism for effecting the desired movement of the fabric;Fig. G is a sectional view taken on the line G-G of Fig. 1; and Fig. 7is a sectional view taken on the line 7-7 of Fig. 1.

The machine, as illustrated in the drawings, has a frame comprising thelongitudinal lower beams 1 supported upon the bearings 2, thelongitudinal top beams 23, the end struts 4 through which the beams 1support the ends of the beams 3 and the bed 5, and the intermediatestruts or bearings 6 which are supported by the beams 1 and support theparts 3 and 5.

Bearings 6 are anchored at the forward end of the machine and a shaft 7is journaled therein, the shaft having fixed thereon the belt wheels 8(containing the peripheral recesses 9) and the register wheels 10containing the notches 11.

A press at the rear of the machine comprises the head 12 liXed by thebolts 18, and the platen 14 movable vertically beneath the head by thepistons 15 acting in the cylinders 16. Links 17', pivotally connected tothe table 5 and platen 14, serve to support a movable continuation ofthe table to the platen.

Bearings 18, fixed to the platen 14, carry journal blocks 19 adjustablelongitudinally by the screws 2O and a shaft 21 journaled in theseblocks, the shaft having lined thereon the belt wheels 22 (containingthe peripheral recesses 23) and the sprocket wheel 24.

Steel belts 25, provided with the cleats Q6 for engaging the recesses 9and 23 and the pins Q7 for engaging a backing fabric 28, are carried bythe wheels 8 dhd22 over the table 5 and platen 14, the fabric beingdrawn from a roller 29, journaled in the bearings 30, under the rollers3l.

A vertically movable frame is formed by the longitudinal side .bars 32and the transverse end bars 33, this frame carrying trays 34 adapted forholding the variously colored granulated composition from which thevarious tessera: of the design are to be formed and having in therespective bottoms thereof apertures 35 and 3G corresponding to theseveral e'ures of the design.

Slides 37 are hired to the side bars 32 and are movable vertically inthe ways formed by the bearings 6 and the guides 38 fixed thereon, theslides carrying the bearings 39 of the wheels 40 which are adjustable inele vation by screws 41 journaled in lugs 42 on the body of the slidesand threaded in lugs 43 on the bearings.

A bar 44, provided with cams 45 for engaging the rollers 40 to effectthe elevation of the trays 34, is movable longitudinally on the wheels46 which are journaled in the yolres 47, the latter being fulcrumed atone ond on the bearings 4S and adjustable at the other end by the screws49 passing there through into engagement with the bearings 50, wherebythe rollers are vertically adjustable to regulate the elevation of thebars 44.

Cams 51 at the forward ends of the bars 44 are adapted for engaging therollers 52 of angle levers which are respectively fulerumed on bearings54 and provided with dogs 55 adapted for entering the notches 11 of thewheels 10, Alining the shaft 7 and the wheels 8 in the desired position,and, through the belts Q5, positioning the backing fabric 28 on thetable 5.

A cam 57 on one of the bars 44 is adapted for rocking an arm 5S fixed ona journaled shaft 59 which is provided with the lugs GO for elevatingalternately the valve rods G1 chain 85 provided With the cam 86.

of a hydraulic valve 62, the latter connecting pipes 63, communicatingwith the cylinders 16, alternately With the feed pipe 64 and the exhaustpipe 65.

A motor 66 drives a belt 67 Which passes over a pulley 68 revoluble on ashaft 69 which is journaled in bearings 70, the pulley being fixed tothe shaft by a clutching mechanism 71, operated by a yoke 72 Which isoperated by a rod 73 movable longitudinally on the bearings 74 by anyone of the several handles 75. A ivorm 76 on the shaft 69 engages a WormWheel 77 fixed on a shaft 78 which is onrnaled in the bearings 79, thelatter shaft having pinions 80 fixed thereon. crank shaft 81, ournaledin the bearings 82, has fixed thereon the spur Wheels 83 which engagethe pinions 80 and the sprocket Wheel 84 which carries the i pitman 87is operated by the crank shaft 81 and operates the arms 88 pivotallyconnected thereto by the pin 89 and journaled on a shaft 90 revoluble inthe bearings 91, the

pin having a Weighted paivl 92 fixed thereon. A ratchet Wheel 93 isfixed on the shaft 90 and is adapted to be engaged on the for- Wardmovement of the paivl 92 when oscillated with the arms 88 by the pitman87. A

lever 94 is adapted to be oscillated on the shaft 90 by a rod 95 whichconnects it to an arm 96 fnlcrumed on the bearing 97, the arm having aroller 98 which is engaged by the cam 86 to move the cam end 99 of thelever 94 aO'ainst the linger 100 fixed to the pin 89 to disengage thepaivl 92 from the Wheel 93. As the cam 86 leaves the roller 98,following the disengagement of the paWl 92, it engages a roller 101 on alever 102 Which is fulcrumed on a bearing 103, the

lever carrying a brake band 104 which engages a brake pulley 105 fixedon the shaft .90. The shaft 90, thus turned in a step by step movement,has a spur Wheel 106 thereon which engages a pinion 107 fixed on theshaft 7, the latter being turned intermittently and moving the belts 25intermittently over the table 5 and platen 14.

A pinion 108, xed on the shaft 69, en-

gages a pinion 109 fixed on the Worm shaft 110 which is journaled in thebearings 111. A shaft 112, journaled in bearings 113, has fixed thereona Worm Wheel 114, Which engages the Worm of the shaft 110, and pinions115 which engage the spur Wheels 116 journaled in the bearings 117. Aneccentric or crank pm 118 is revolved by the Wheels 116 and operates thepitman 119 connecting it with the bearing 120 on the cross bar 121connecting the cam bars 44.

The mechanisms connecting the shaft 69 With the Wheels 8 and With thebars 44 are timed in their operations so that these Wheels act toadvance the belts 25 with the 55 cloth thereon lfollowing the action ofthe bars which causes the cams 45 to elevate the slides 37 and the frame32 With the trays 34 thereon so that the latter shall clear the tessereeplaced on the backing fabric, and as the bars 44 Withdraw the cams 45from the rollers 40 so that the trays move downwardly to engage thebacking fabric, the cams 51 engage the rollers 52, rock the angle levers53 and throw the dogs 55 into corresponding notches 11 to fix the fabricin the desired relation to the trays, through the apertures in which thecomposition is pressed upon the backing fabric. Simultaneously with themovement of the cams 45 under the rollers 40, the cam 57 elevates thearm 58 and rocks the shaft 59, causing a lng 60 rthereon to elevate arod 61 by which the valve 62 is operated to open communication betweenthe pipes 63 and 65, permitting the cylinders 16 to exhaust and theplaten 14 to fall.

The sprocket Wheel 24 is connected by a chain 122 with a sprocket wheel123 which is fixed to a spur Wheel 124, the Wheels 123 and 124 beingjournaled on a shaft 125 fixed t-o the head 12. Arms 126, adapted torock on the shaft 125, carry a roller 127 to which is ixed a spur Wheel128 connected with the spur Wheel 124 by an idler 129 journaled on oneof the arms. The roller 128 frictionally engages a fabric 130 on aroller 131 journaled in the bearings 132, the fabric being drawn underthe press .head 12 from the roller 133 journaled in the bearings 134, ina step by step movement corresponding to that of the fabric carried b vthe belts 25, and preventing the tesserae from sticking to the presshead.
